我如何知道是什么阻止了 Ubuntu 上的睡眠？我的盒子不会自动休眠！

Question

从菜单手动休眠我的 Ubuntu 桌面工作正常。我已将“5 分钟”的首选项设置为“不活动时暂停”。然而，计算机经常不睡觉。

在 Windows 上，我powercfg -requests用来查看滞留情况。在 Mac 上，我可以pmset -g assertions用来查看是什么阻止了睡眠（Source）。

我认为 Chrome 可能会阻止睡眠，但我不能确定。

是否有 Linux 等效的方法来查找？可以的PowerTOP这样使用？

Answer 1

您需要找到抑制剂，也就是哪些进程阻止了您的挂起：

systemd-inhibit --list --mode=block

这将列出不想“想睡觉”的进程

Answer 2

你必须设置：

• 系统设置 > 电源设置为 10 分钟后关闭。
• 系统设置 > 亮度并锁定以在 10 分钟后关闭屏幕。

对于电池和“插入时”：

$ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 300
$ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 300

您还可以设置：

org.gnome.settings-daemon.plugins.power sleep-display-battery的值低于以下值 sleep-inactive-battery-timeout
